Bad spark plugs, fouled-up plug wires or a cracked distributor cap can cause spark loss, while compression loss — in which too much of the air-fuel mixture flees a cylinder before going bang — commonly arises from a leaky exhaust valve or a blown head gasket [sources: B&B; O’Reilly].
When any changes are made to the engine of a car, the ignition timing is adjusted accordingly. If not, you could experience several problems with your engine with improper ignition timing like knocking, hard to start, increase fuel usage, overheating, and reduced power.
The distributor cap are tasked with passing voltage from the ignition coils to the engine’s cylinders through the spark plug wires and plugs themselves to ignite the air and fuel mix. A failing distributor cap will result in rough idle because the voltage is not being sent to the plugs at the proper time, or at all.

Axial play (up/down) should be kept to between 0.010″ and 0.020″. Shims are available to properly set the axial play, but rotational play is set by the gear on the bottom of the distributor shaft and how it meshes into the gear on the back of the cam.
The rotor is attached to the top of the distributor shaft which is driven by the engine’s camshaft and thus synchronized to it. Synchronization to the camshaft is required as the rotor must turn at exactly half the speed of the main crankshaft in the 4-stroke cycle.
Luckily, most distributors can be rebuilt, unless they are damaged or weathered beyond repair. Your car’s distributor sends the flow of high-voltage electricity from your coil to each of the engine’s cylinders. … The sparking action must speed up — or be advanced — as the engine runs faster.
The most likely issue is a clogged fuel filter. … While the fuel filter is the most common problem with the fuel system and is the easiest to fix, a lack of power could also point to issues with the fuel line or the fuel pump.

The distributor cap, rotor and spark plugs could make it longer, and were often replaced at the 30,000-mile (48,280-kilometer) tune-up. Spark plug wires held out the longest, with a recommended change at around 90,000 miles (144,841 kilometers).
While a shaky idling car can certainly feel like an earth-rumbling tremor, it can also indicate a problem with the engine. One common cause of shaking while idling can be loose engine mounts. … Alternatively, a car that shakes when idle may have faulty fuel injectors, worn-out spark plugs, or a bad timing belt.
An acceleration problem is usually the result of insufficient fuel, air, or spark during the combustion process. Worn-out spark plugs or the electrical cables attached to them are one of the most common causes of cars stuttering.
